Sr. ) is a radioactive isotope of strontium produced by nuclear fission, with a half-life of 28.8 years. It undergoes β − decay into yttrium-90, with a decay energy of 0.546 MeV. [2] Strontium-90 has applications in medicine and industry and is an isotope of concern in fallout from nuclear weapons, nuclear weapons testing, and ...

Estroncio-90 es un isótopo de estroncio radiactivo producido por fisión nuclear, con un periodo de semidesintegración de 28,8 años. Sufre β - decaimiento en itrio-90, con una decaimiento de energía de 0.546 MeV. [2]
5 de feb. de 2024 · Strontium (chemical symbol Sr) is a silvery metal that rapidly turns yellowish in air. Naturally occurring strontium is not radioactive. The most common man-made radioactive form of strontium is strontium-90 (Sr-90). Strontium-90 is produced commercially through nuclear.
Strontium-90 is a chemical substance with radioactive properties. Read on to know all about its properties, uses and its effects on human health. What is Strontium-90? It is a radioactive substance that radiates “Beta Rays”. It is one of the radioactive isotopes of the chemical named Strontium (Sr). History of Strontium-90 Origin
Mode of decay: Beta radiation. Chemical properties: Chemically reactive; can create halide, oxide, and sulfide compounds. What is it used for? Because Sr-90 generates heat as it decays, it is used as a power source for space vehicles, remote weather stations, and navigational beacons.
Strontium-90 behaves like calcium in the human body and tends to deposit in bone and blood-forming tissue (bone marrow). Thus, strontium-90 is referred to as a "bone seeker," and exposure will increase the risk for several diseases including bone cancer, cancer of the soft tissue near the bone, and leukemia.
